Yes, it is a registry problem. Following is part of the Microsoft article Q169620 detailing how to modify the registry to fix....

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

Start Registry Editor (Regedt32.exe).

Go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\Legacy_Cdrom\0000.

On the Registry menu, click Save key and call it 000.reg.

Go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\Legacy_Cdfs\0000.

Click the 0000 key, and then click Permissions on the Security menu.

Change the 0000 key permissions to Everyone : Full Control, and then click OK.

On the Registry menu, click Restore, and restore the 000.reg key saved from step 3 on top of the current 0000 key under Legacy_cdfs.

Under the restored 000 key, modify the following two entries:

Change DeviceDesc:REG_SZ:Cdrom Device to Cdfs Device.

Change Service:REG_SZ:Cdrom to Cdfs.

Exit Regedt32.exe and then restart Windows NT. The CD-ROM drive should now work normally.
